原始文件的说明

第一个产品系列始终以VL开头，然后按此顺序继续：

type;Productnumber;Productname;Description;measurement_unit;price_unit;price_unit_txt;price;crowd;price_date;status;block_number;discount_group;manufac;type;stocked;sales_package;discount;price_type;

PDF         is always on a new line starting with VX;PDF;
IMAGE       is always on a new line starting with VX;IMAGE;
baseinfo    is always on a new line starting with VX;BASEINFO;
WEIGHT      is always on a new line starting with VX;WEIGHT;
VOLUME      is always on a new line starting with VX;VOLUME;
dimensjon   is always on a new line starting with VX;DIMENSJON;
UNSPSC      is always on a new line starting with VX;UNSPSC;
va_2        is always on a new line starting with VA;2;
va_3        is always on a new line starting with VA;3;

希望有人可以帮助我解决这个问题：）

一种可能的方式（不是解决方案）

#!/bin/bash

awk -F';' '
    function init() {
            # formation line to print_line
        line = vl pdf image baseinfo  weight volume dimensjon unspsc va_2 va_3 
            # erase ^M (\r)
        gsub( /\r/;"";line )
            # print a block
        print line
            # initialisation variables
        vl = pdf = image = baseinfo  = weight = volume = dimensjon = unspsc = va_2 = va_3 = ";"
    }
        # head/title, note that "%12s" format with 12 characters width
    BEGIN { printf ( "%12s; %s; %s; %s; %s; %s; %s; %s; %s; %s;","vl","pdf","image","baseinfo ","weight","volume","dimensjon","unspsc","va_2","va_3" ) }
    /^VL/ { init(); ; vl = sprintf( "%12s; %s; %s; %s; ", $3, $4, $5, $6 ) }
    /^VX;WEIGHT;/ { weight = sprintf( "%s; ", $3 )}
    # .. another conditions
    END { init() }
' file.dat  # > outputfile.csv

进行测试：

cat << end > file.dat
VL;1;1001;Productname 1;Description 1;2;MTR;METER;217883;10000;20180402;1;010206;&10;PRODUCER1;;N;10000;;
VA;2;4044773815245;V;
VA;3;0036453;V;
VL;1;1002;Productname 2;This is product decrtiption for 2 product;2;MTR;METER;140365;10000;20180402;1;010206;&10;PRODUCER1;;N;10000;;
VX;WEIGHT;7500
VX;VOLUME;3249

VX;UNSPSC;26121616
VA;2;7070613017149;V;
VA;3;1000116;V;
end

输出中

      vl; pdf; image; baseinfo ; weight; volume; dimensjon; unspsc; va_2; va_3;
    1001; Productname 1; Description 1; 2; ;;;;;;;;;
